Flexible Displays for Digital TV Broadcasting

Flexible displays using plastic film substrates are key devices for ubiquitous and universal services of digital broadcasting because of their mobile characteristics, low cost productivity, and flexibility of viewing style and so on. Polymer organic light-emitting devices (P-OLED) and ferroelectric liquid-crystal (FLC) films composed of ferroelectric liquid crystal and polymer network are promising display devices and materials for reproduction of TV images, where gray-scale and high-speed response characteristics are required. Both prototype flexible displays of P-OLED using phosphorescence materials and A4-sized FLC have been fabricated. Performances of these displays showed substantial potential for ubiquitous and universal digital broadcasting services
